You said the smodem drivers got it working with a PCT789?
I just tried, on Fedora Core 2. The stuff modprobes fine, but when I open the device in minicom all of the init's work fine but if I actually try to dial anything it instantly says NO CARRIER.
I looked at the FAQ and it said this will happen if I hit enter twice, but I didn't..
I still don't think this works with the PCT789, which sucks because I am running 2.6 on Core 2.
Any ideas?
